Describe the problem

Changing from rc9.0 to 9.1 sketches aren't uploading for me anymore.

Two things:

1. Using Theia-Light:
   image

The first dark entry on the left is selected. It just shorts the text of the selected entry and switches to "..." earlier.
Same on the right. The usual dark blue like in the board combobox isn't there. According to the combobox the selection does work:

The nightly build has issue 2) as well, but it does look like in regards to 1) it shows a checkmark next to the selected item.

2. Uploading just fails.
   Failed uploading: uploading error: exit status 1

That is all. No warnings, no other errors. I'm using verbose output by default.

I still have a second folder with rc9.0.
It still works flawlessly there.

To reproduce

Use latest build of megatinycore (2.5.11).
Select device with optiboot.
Upload.

Expected behavior

That the sketch uploads

Arduino IDE version

2.0rc-9.1

Operating system

Linux

Operating system version

XUbuntu 22.04 LTS

Additional context

I am using megaTinyCore 2.5.11 and uploading using a USB-TTL adapter and optiboot.
